Purpose: demonstrate surface tension in a counterintuitive way.
Description: Use two identical balloons. Blow up one balloon on the tube and clamp it. Then blow up the other balloon to a different size and slip it onto the other end of the tube.
Q: When you remove the clamp, what will happen?: (a) the small balloon will get smaller and the large one larger, (b) the two balloons will become equal, or (c) they will stay the way they are.
A: The small balloon will blow up the larger one, and get smaller, due to surface tension effects. The rubber is thicker in a smaller balloon, and thus produces greater surface tension.
Availability: Available
